McAfee spoke in a restaurant near a luxury hotel where he is staying in Guatemala City after sneaking out of neighbouring Belize.

Police in Belize have called him a person of interest over the November killing of a fellow American expat, but say there is no warrant for his arrest. Since there are no restrictions on his travels, it is unclear why he would need any special status in order to stay in Guatemala.

McAfee says he is being persecuted by the Belizean government and he has sensitive information about official corruption in that country. He has hired a well-known Guatemalan lawyer to assist him. "I need a safe place where I can actually speak out," McAfee said. "Now that I'm here I can speak freely. I can speak openly."

Belizean police have denied they are persecuting McAfee or are motivated by corruption, saying they have simply been investigating a crime about which McAfee may have information.

Prime minister Dean Barrow has expressed doubts about McAfee's mental state, saying: "I don't want to be unkind to the gentleman, but I believe he is extremely paranoid, even bonkers."

McAfee said he would petition the Guatemalan government to allow him to stay. He said he feared he would be killed if he turned himself in for questioning in Belize. "Belize does not have a good track record of providing safety when they ask to question you," he said. "I felt much more secure crossing the border into a country that had laws that were backed by the justice system."

McAfee is wanted for questioning in connection with the killing of Gregory Viant Faull, who was shot dead in early November on the Belize island where the men lived. Mr Faull's home was a couple of houses down from the compound where McAfee kept several noisy dogs, armed guards and entertained a steady stream of young women brought in from the mainland.

McAfee acknowledges that his dogs were bothersome and that Mr Faull had complained about them, but denied killing him. Several of the dogs were poisoned shortly before Mr Faull's murder. "I am absolutely innocent," McAfee said yesterday.

The Faull family has said through a representative that the murder of their loved one on Ambergris Caye has got lost in the media frenzy provoked by McAfee's manipulation of the press through phone calls, emails and blog posts detailing his life on the run.
